Well i got an assignment where i had to do a character from a concept with the restrictions:
16 color template
Max 70 pixels high and follows a 3x1 Isometric grid.
And here is the outcome.

the eyebrows was my biggest issue here.
C&C welcome.
Hey, from previous posts I can see you have pretty good experience whit isometric stuff....
But there are some inconsistence here if I am not wrong, I never worked whit 3x1 grid but I suppose it looks like the blue line I have on my image...yes? Well there you can see that your sprite is clearly on normal isometric view...correct me if I am wrong.
But hey I still like a lot your sprite, its very detailed...the only part that is bothering me are eyebrows...don't like how they are over the hat.
